PHP ajax real input automatic search matching program code_PHP tutorial

This article will introduce to you the php ajax real input automatic search and matching program code. I hope this program will be helpful to everyone. The first method uses jquery autocomplete, and the second method uses jquery ajax. In fact, both almost.

The simplest way is to use the jquery autocomplete method directly, as shown below in the example

html in

The code is as follows

代码如下	复制代码

The purpose of this article is to allow a title with The to be searched not by the first letter of the letter t, but by the first letter of the second text.

For example, The Orbolg is not displayed when you press T, but is displayed when you press O.

The following is the implementation code. I feel dizzy myself. Testing is no problem.

The code is as follows

public function gwquery(){     if($_POST){     $zm = $_POST['data'];     $wzm = $zm."%";     $b = M('Wpindexgw');     if($zm!="t"){//获取的首字母不是t的时候     $list1 = $b->where("gwstatus=1 and gwname like '%$zm%'")->order("time desc")->select();//查询     $narr =array();     foreach( $list1 as $key => $val){                 $ct2 = explode(" ",$val['gwname']);//获取标题拆分成数组。          $szm=strtolower(substr($ct2[1],0,1));  //获取首字母 并且小写         if($ct2[0]=="The" && $szm==$zm){//如果第一个字符是The 并且第二个字母首字母和提交的相同，这里The 区分大小写。         $narr[] = $val; //写入数组         }        }     }else{      //处理首字母是T的时候    ，不希望第一个字数The 的显示在列表里。         $list1 = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();     foreach( $list1 as $key => $val){                 $ct2 = explode(" ",$val['gwname']);         if($ct2[0]=="The"){         $unnarr[] = $key;//获取符合条件的，要去掉的内容的数组标号。              }               }                  }     $list = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();//正常的查询。     if($zm=="t"){//处理当首字母是t的时候 ,去掉上面查询得到的内容，也就是如果是The的时候 按T 不显示。     foreach($unnarr as $uval){         unset($list[$uval]);     }                }else{//按下的不是t的时候，要把第二个首字母符合的内容添加到正常查询的数组中。     if(!empty($narr) && !empty($list)){//带The 的符合条件正常 本身也不空的时候。     $list = array_merge($narr,$list);//合并数组。     }else if(empty($list)){//正常查询为空。则看是否有带The开头的，有则合并     $list=array();     $list = array_merge($narr,$list);        }     }     if($list){     $this->ajaxReturn($list,'success',1);     }else{         $this->error("Bestiary not found.");         }     }       }

public function gwquery(){

$wzm = $zm."%";

相比之前的代码：相差太多

 代码如下

代码如下	复制代码
public function gwquery1(){//之前备份。。     if($_POST){     $zm = $_POST['data'];     $wzm = $zm."%";     $b = M('Wpindexgw');     $list = $b->where("gwstatus=1 and gwname like '$wzm'")->order("time desc")->select();     //dump($list);     if($list){     $this->ajaxReturn($list,'success',1);     }else{         $this->error("Bestiary not found.");         }     }       }
